Neil Young has departed from his role as CEO of DeNA’s ngmoco, and will be replaced by Clive Downie. Co-founder and CCO Bob Stevenson has also stepped down.

Both Young and Stevenson are co-founders at Ngmoco. The casual game publisher was a breakout star of the App Store and acquired long-time Apple developer Freeverse, which also made a splash in the App Store. In August, Freeverse co-founders Ian and Colin Lynch Smith left the company, which suffered layoffs shortly thereafter.
